TLK3114SBGNT

Drivers, Receivers, Transceivers Overview

The TLK3114SBGNT is a quad serial transceiver from Texas Instruments designed for high-speed, bidirectional point-to-point data transmission. It delivers up to 10 Gbps of aggregate throughput with four independent channels operating at rates between 2.5 Gbps and 3.125 Gbps. The device supports IEEE 802.3ae 10-Gigabit Ethernet standards, including XGMII parallel interfaces and XAUI serial links. It integrates selectable 8-b/10-b encoding and decoding functions, on-chip receive equalization, and an MDIO management interface. Powered by a single 2.5-V supply, it dissipates less than 3 W and is housed in a 19-mm × 19-mm, 289-terminal plastic ball grid array package.

Drivers, Receivers, Transceivers Feature Summary

• Supports synchronized or independent channel operation for flexible system integration
• Integrates on-chip 8-b/10-b encoder/decoder and receive equalization circuits
• Features VML serial drivers providing PECL-compatible differential signaling without external components
• Includes built-in PRBS generation and verification for self-test capabilities

Drivers, Receivers, Transceivers Applications

• Chip-to-chip implementation as an XGMII extended sublayer (XGXS) device
• Providing the 10-Gigabit Ethernet physical coding sublayer (PCS) to optical transceivers
• System backplane interconnect applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure that the design environment meets the required electrical specifications and signal integrity guidelines for high-speed serial interfaces.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad-channel solution is required for 10-Gbps Ethernet applications. It serves as a terminal-compatible replacement for the TLK3104SA, allowing for direct board design upgrades while maintaining support for both XGMII and XAUI protocols.

Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments CMOS multi-gigabit transceiver family. It is specifically engineered for high-speed bidirectional data transmission over controlled-impedance media such as PCB traces, copper cables, or fiber-optic links.

Drivers, Receivers, Transceivers Replacement Considerations

The TLK3114SB is terminal compatible with the TLK3104SA. Designers upgrading from the TLK3104SA can utilize existing board layouts without pinout modifications.
